Federal Severe Storm ExtensionsIRS frequently issues two-month automatic extensions, including abatement of interest and penalty, from the date that a severe storm hits your area. Check the list of storm extensions here. The abatement period applies to all taxes, including those assessed subsequent to filing the return. This can result in a substantial tax savings. State severe storm extensions don't necessarily follow the federal extension, so check the state filing status separately.

State Tax AmnestiesDelinquent on your state tax obligations? Check whether your state has instituted (or recently concluded) a tax amnesty. These usually run just two or three months, so hurry.
